' V BICYCLE-ALARM.

SPECIFICATION forming part of Letters Patent No. 543,418, dated July 23, 1 895.

Application filed October 29, 1894. Serial No. 527,252. (No model.)

To all whom it may concern:

Be it known that I, RAYMOND M. BEATTY, a citizen of the United States, residing in Newark, in the county of Essex and State ofV New Jersey, have invented certain new and useful Improvements in Alarms for Velocipedes, of which the following is a specification. This invention relates to alarms in the nature of bells, whistles', dac., used on bicycles or other velocipedes.

The object of the invention is to provide an improved construction of alarm mechanism which shall present a more workman-like appearance on the handle-bar of the machine,

and be more easy and certain in operation than the alarm devices .heretofore used.

To this end according to my invention I construct one of the handles to be movable upon the handle-bar, preferably by rotating thereon, and I construct the alarm mechanisml to be actuated by such movement of the handle relatively to the handle-bar. The

alarm mechanism is constructed so as to be mounted concentrically upon the bar, appearing as an annular concentric projection therefrom. i

Figures l to of the accompanying drawings show my invention as applied. to an alarm-bell. Fig. l is an elevation of the head and handle-bar, showing the loose handle A and the alarm mechanism B as applied there-` to. Fig. 2 is an elevation of this handle and alarm upon a larger scale. Fig. 3 is a longitudinal mid-section thereof. Fig. 4 is a ,transverse section on the line 4,4 in Fig. 3. Fig. 5 is a transverse section on the line 5 5 in Fig.

.- 3, the bell being removed. Figs. 6 to l2 illusv trate a modication wherein the alarm mechon the line 10 ll, Fig. 10, looking to the left in Fig. S, and Fig. 1l looking to the right in that figure. Fig. l2 is a development or plane projection of the annular or cylindrical arrangement of cams shown 'in Fig. 8.

I will first describe the construction shown in Figs. l to 5, where the alarm consists of a bell. A On the handle-bar O of a bicycle, or

other velocipede are arranged two handles A Vthe bell the rider has only to rotate the handle in either direction for a portion of a revolution, which is easily and conveniently done by a twisting movement of the hand which grasps the handle. A turn of from one-fourth to one-third of a revolution will cause the bell to be struck several times in quick succession,

giving a sharp and distinct alarm, which-is repeated 4it' the rider carries the handle back by Va return movement of his hand.

The construction'shown is that which is preferred, but may be greatly varied in practice. The handle and belly mechanism are mounted on a tube or sleeve a, Fig. 3, which stube is detachably secured to the handle-bar C by any suitable means, preferably by a setscrewb. The handle A is mounted on a sleeve c, which'fits freely over the tube a, so as to be turned easily thereon.` On this sleeve cis also mounted a disk d,- which is fixed thereto so that through the medium of the sleeve the.

handle A and disk d are connected together, so that by the turning of the handle the disk also is turned.

is closed bya cap e, as usual. To keep the Theother end of the handle handle from slipping off or moving longitudilspring q, being stopped by a pin q.

plates g g fastened by screws to the disk d.

The opposite end of the sleeve a is preferably thickened by having a ring d attached to it by brazing or otherwise, on which ring is screwed the hub of a bell or gong j. The open mouth of this bell or gong is nearly closed by the diskd, which, however, does not touch it. For ringing the gong a hammer k is provided, mounted on a flexible arm Z projecting from a cam-lever m having a V tooth or projection fm', which is acted upon by the teeth of a cam-wheel p. When pressed out by any of the teeth of this wheel to throw the hammer against the gongit is retracted by a The lever m and springy q are both mounted on the disk d, so-that by the rotative movement of the handle A they are carried around inside the bell, and the tooth m is consequently moved past the cam-teeth of the wheel p, which is held immovable by being attached to the sleeve d, preferably by being formed integrally with the sleeve t' which is fastened thereto.

A bicycle-bell thus constructed has a very neat and compact appearance, having the effect of being a part of the machine, rather than being a mere attachment thereto. It is operated with the greatest ease and safety, as the rider does not have to remove his hand or any portion thereof from the handle, so that in an emergency requiring the ringing of the alarm he retains full control of his machine.

I will now describe the modification illustrated in Figs. 6 to 12. The movable han die A is here of the same construction al` ready described, being mounted on a tubular sleeve 0f,v in the same manner. The alarm mechanism, here lettered B, 'consists of a whistle or whistling device. On the inner end of the sleeve a is fixed ashell D', which may be formed of stamped-up sheet metal, while to the rotary sleeve c is lixed a disk CZ having a flange d2 which meets and fits within the shell D', turning freely thereon W'ithin the shell D is partitioned olf an annular chamber C', constituting a reverberatory-chamber, and back of this is a piston-chamber E in which works a piston-plate or diaphragm F, which normally occupies the position shown in full lines, but which may be pressed forward to the position shown in dotted lines, being then returned by the tension of a spiral spring Gr. This movement of the plate F to the dottedline position compresses the air in the chamber E and eXpels it through a minute outletnozzle r, which directs the jet of air through the outlet-opening r', causing the air in chamber C to vibrate, thereby producing a sharp loud musical note, after the manner well unplace in the same manner as in the construc tion first described-that is to say, I provide an inwardly-projecting flangef, engaging an outwardly-projecting flange h. The former is constructed on a plate or ring g', fastened by screws to the disk d', and formed at one side with a projecting fork s, between the arms of which is embraced a movable pin t. The flange h projects from a ring or sleeve t" fixed to the sleeve a. This ring t", however, is cutor notched on its front edge in zigzag fashion with alternately outwardly and inwardly progressing inclines or cam-faces. On the rear side of the piston F is fastened a similar ring or cam I, the rear edge of which is formed with like angular cam-faces. Between these two rings vl and I are arranged` successive diamond-shaped cams J J, which are connected together through the medium of a ring fu, extending outside of them and riveted or otherwise fastened to them. The cam-plates J J are cut as segments of a tube closely fitting the sleeve a, so that the inner faces of the cam-plates are seated and guided thereon. The pin t projects from one of the plates J, or it might project from the ring t?. The piston F is guided and prevented from revolving by longitudinal ribs or keys w w, lixed on the inner side of the shell D.

The operation is as follows: By turning the handle A the disk d and fork s, fixed thereto, are causedto revolve around the sleeve a, and by the action of the fork against the pin t this revolving motion is communicated to the cam-plates J J and their connectingring fu. As the cam-rings t" and I cannotfrevolve and as the former is immovable, the effect of this movement of the cam-platesJ J is to cause them to act as Wedges, pressing between the oblique cam-faces of the rings t" and I, so that the latter ring is forced forward against the tension of the spring G, the rotation of the ring and piston being prevented by the ribs w. This motion continues until the widest portions of the diamond-plates J have passed the most salient portions of the projections on the cam-rings t" and I, whereupon by the continued rotation the pressure is relaxed and the spring is permitted to press back the piston F to its normal position. If three cam-plates J J are employed, as indicated, then one-sixth of a revolution of the handle in either direction will impart the necessary motion to the piston to cause one IOO IIO

blast to be blown by the whistle, and the movement may then be continued in the sameV direction to restore the piston, or it may be restored by an equal return movement.
